摘要
从谐波的定义、谐波的国家标准、地铁供电系统谐波产生的原因、谐波对供电系统各设备的危害等方面分析了谐波治理的必要性。根据西安地铁供电系统的谐波治理方案,介绍了低压有源电力滤波器在谐波治理中的应用。通过仿真试验和理论分析,验证了治理方案的可行性,保证了供电系统的电能指标满足国家标准。
The necessity to govern the harmonic wave is an- alyzed from the aspects of the definition, national stand- ards, procreant reasons and the harms of harmonic wave to various equipments in subway power supply system. Ac- cording to the government plan of harmonic wave in Xi＇an subway supply system, the application of low pressure ac- tive electric power filter in the harmonic wave government is introduced. Through a simulation and the theoretical a- nalysis, the feasibility of the government plan is con- firmed, which will guarantee the guide line of electrical en- ergy to satisfy national standards.
